Measuring 16 oz (1 lb) of Caster / Superfine Sugar in the Kitchen

Because 1 US Customary Cup (236.6 mL) of caster / superfine sugar weighs 225g when measured poured & leveled, 16 Ounces (453.6g) translates to 2.02 US cups (2 cups + ¾ tsp). By contrast, using the spooned into cup measure (215g/cup — a 10g per-cup shift), 16 oz occupies 2 ⅛ cups (2.11 cups).

Without a kitchen scale, measure 2 cups + ¾ tsp (32.26 tablespoons total) using poured & leveled technique. Pour and level flat. Because the micro-granules pack closer together than regular granulated sugar, 1 cup weighs a dense 225 grams.
